Question

Refractive index of medium 3 id
greater than refractive index
of medium 2. So, which medium
is optically denser ​

Answer 1

Answer:

For optically denser medium, refractive index n1 is greater than that of the rarer medium n2. Thus, the angle of refraction has to be greater than angle of incidence i.e. it bends away from the normal.

Answer 2

Answer:

Medium 3

Explanation:

Denser the medium refractive index is more, rarer the medium refractive index is less
